Problems solved by technology

However, this technology has the problem that if a high heat of more than 200 degrees is applied to the microphone, the heat will cause the electrons stored on the electret to disappear, resulting in a decrease in product performance.

Abstract

The present invention relates to a silicon condenser microphone. The purpose of the present invention is to manufacture a condenser microphone with the surface mounting (SMT) of a microphone by removing electrets on a back plate. The condenser microphone of the present invention includes a high-voltage generator in a microphone controller such that a diaphragm of a microphone sensor is electrified with a high voltage. Thus, the diaphragm of the microphone sensor is electrified with a high voltage in the high-voltage generator in the microphone controller to remove the electrets on the back plate to have no influence of a high temperature during reflow for SMT, thereby enabling the SMT process without deterioration of sensitivity. In addition, the diaphragm (210) of the microphone sensor is not in electric contact with a microphone case to prevent the inflow of noise caused by an external noise such as electronic waves applied to the microphone case.

Description

technical field [0001] The present invention relates to a silicon microcapacitance microphone, in particular to a vibrating plate of a microsensor to generate a high voltage, the loudspeaker control part is equipped with a high voltage generating part, and the electret (electrets) is canceled on the back plate, by having a heat-resistant Construction, by SMT (Surface Mount), silicon microcapacitor microphones can be manufactured microphones. Background technique [0002] In general, a condenser microphone is a microphone that converts sound into an electrical signal based on a change in capacitance. [0003] The traditional condenser microphone mentioned above such as figure 1 As shown, it is composed of the following parts: a loudspeaker box (100), which is made of metal, and a sound hole is arranged on it; a motherboard (PCB) (400), which mounts the above-mentioned loudspeaker box made of metal (100) microsensors provided inside and a microphone control unit (300) electr...
